* Remove redundant software scaler warning and exit in the sws_func() function for the config file
* Added support for the experimental software scaler
* Lower psy-rdoq from 2.5 to 1.5 and psy-rd from 2.5 to 2.0 to eliminate ringing artifacts
* No need to enclose the values of max-cll in quotes

ChangeLog for ffx264 3.4.4

* Remove redundant software scaler warning and exit in the sws_func() function for the config file
* Added support for the experimental software scaler
* Added support for software scaler tuning where applicable
* Removed additional encoder info on max audio channels support

* Replace numbers in array variable char of the video_chars_func() function with the ones from the for loop
* Pipe the ffprobe string to tail -1 to work around issues with some problematic files
* Some small improvements to the video_colorspace_func() function

* Make software scaler tweaking optional
* Added support for the unsharp filter for sharpen/blur
* Use a colon symbol as separation for input/output color range in the video_colorspace_func() function as to be consistent with the other options. Also set the default to tv:tv

* Bugfix: use realpath instead of readlink for the OUTPUT var when running in batch mode. Fixes the issue where readlink will follow the full path in case the input is a symlink which may result of encoding files we were not asked to
* Don't print cropped resolution during runtime if batch mode is selected
* Remove check for realpath. It is now required and not optional
